Bitwarden vs Proton Pass

Open-source passwords: a real free tier and the lowest paid price

Open-source passwords with email aliasing baked in, from Swiss Proton

The two open-source privacy favorites, closer than any other matchup we've scored: both audited, both with real free tiers, both under $25/year. Bitwarden's 2026 price rise turned what used to be a landslide into a genuine coin-flip decided by features.

Round-by-round scorecard

32 (1 even)

BitwardenProton Pass
  1. Round 1Free tierProton Pass takes it

    Both offer unlimited passwords and devices free; Proton adds passkeys everywhere plus 10 email aliases. Bitwarden's free plan keeps 2-person sharing — but Proton's is broader overall.

  2. Round 2Priceeven

    $19.80/yr (Bitwarden Premium) vs $23.88/yr (Pass Plus) — effectively level since Bitwarden's Jan 2026 doubling; family plans differ by shape (6 users both, $47.88 vs ~$60).

  3. Round 3Email aliasingProton Pass takes it

    Unlimited hide-my-email aliases with custom domains are built into Pass Plus; Bitwarden only integrates external forwarding services.

  4. Round 4Maturity & ecosystemBitwarden takes it

    Bitwarden is a decade old with enterprise tiers, native apps and the category's best third-party integration story; Proton Pass launched in 2023.

  5. Round 5Self-hostingBitwarden takes it

    Bitwarden (and its Vaultwarden community server) can run entirely on your hardware; Proton Pass cannot.

  6. Round 6Offline accessBitwarden takes it

    Bitwarden's free tier includes offline read access; Proton Pass paywalls offline mode entirely.

Where each one wins — and hurts

Bitwarden

  • Open source and independently audited, with optional full self-hosting — a unique trust story
  • The only mainstream free tier with no device or password caps
  • Cheapest paid tier in the category even after doubling: $19.80/yr vs 1Password's $47.88
  • Jan 2026 Premium upgrades: vault health alerts, phishing blocker, 5 GB storage
  • Utilitarian UI and occasionally less reliable autofill than 1Password, per most 2025-26 reviews
  • The Jan 2026 price rise (~2× from $9.99/yr) was poorly communicated and dented its value halo
  • Offline access is read-only — you can't edit your vault without a connection

Proton Pass

  • The most generous free tier of the major managers: unlimited passwords and devices
  • Built-in hide-my-email aliasing (SimpleLogin infrastructure) that no rival matches natively
  • Open source, independently audited, Swiss jurisdiction, nonprofit-foundation controlled
  • Rapid shipping: offline mode, CLI, credit-card autofill and team groups all landed in 2025
  • Offline access and the TOTP authenticator are paywalled — the free plan is online-only
  • Desktop apps are web wrappers rather than native
  • Younger product with thinner enterprise tooling than 1Password or Bitwarden

The decision

Choose Bitwarden if…

You want the proven, boring choice: a decade of audits, self-hosting freedom, enterprise depth and offline access even on free. Bitwarden remains the default recommendation of the open-source world.

Try Bitwarden

Choose Proton Pass if…

You want aliasing — the single best everyday privacy upgrade — bundled with your passwords, or you're already in the Proton ecosystem (Mail, VPN, Drive). Pass Plus at $1.99/month is the richer consumer bundle.

Frequently asked

Are both really open source?

Yes — both publish client and server code and commission independent audits (Bitwarden regularly, Proton via Cure53). Bitwarden goes further by supporting self-hosting; Proton counters with Swiss jurisdiction and nonprofit-foundation control.

What's the deal with email aliases?

Proton Pass creates unlimited hide-my-email addresses (via SimpleLogin infrastructure) so every site gets a unique address you can kill when it leaks or spams. Bitwarden can generate aliases only through third-party services you set up separately. If aliasing matters to you, this round alone decides the matchup.

Which free plan is better?

Both are genuinely usable — unlimited passwords and devices on each. Differences at the edges: Bitwarden free includes offline access and 2-person sharing; Proton free includes passkeys on all platforms and 10 aliases but is online-only. Pick by which edge case is yours.

Can I migrate between them?

Yes, trivially: both export/import standard formats (JSON/CSV) and each documents importing from the other. As always, passkeys need re-registering per site after a switch.
